Dialer Profiles and Dialer Rotary Group Configuration

This section is divided into two portions:

Each part briefly describes the general configuration tasks involved in setting up dialer profiles and rotary groups. These tasks and the specific commands needed to configure them are described in more detail in the "Scenarios" section for both dialer profiles and rotary groups.

Configuring Dialer Profiles

Dialer profile configuration involves three separate stages:

  1. Configure the logical dialer interface.

  2. Configure the physical interface as a member of a dialer pool. At this stage you also specify the service parameters for the physical interface.

  3. Optionally define the map class.

Let's briefly look at some commands that let you configure dialer profiles. A number of commands involved in this process create relationships between the elements of a dialer pool. Some of these commands belong to the physical interface configuration portion, and others belong to the dialer interface.

Among the dialer interface commands is the dialer string command, which specifies the destination's phone number. Multiple phone numbers may be included using dialer string. Starting with Cisco IOS Release 12.2(8)T, you can specify the order in which these phone numbers are to be used. Within the dialer string command, you can include the optional keyword class, followed by the map-class-name parameter. When used, they specify a particular map class and pull the configurations from that map class for the call.

Another portion of the dialer profile configuration is to specify the pool of physical interfaces used to reach the target network. The pool is identified by a number between 1 and 255.

You can then associate a physical interface with a numbered pool and place the interface in that pool using a special physical interface command described in Scenario 7-1.

To make your configuration completely functional, two extra steps need to be taken:

  1. Specify "interesting" traffic that will cause the link to be brought up.

  2. Define the static routes to be used.

Configuring Dialer Rotary Groups

Five configuration stages set up dialer rotary groups:

  1. Define interesting traffic.

  2. Create a dialer interface.

  3. Configure the physical interfaces as a rotary group.

  4. Configure static routes.

  5. Disable routing updates.
